Kawasaki John Deere ignition modules

[The Boat House]

Taking a break from this project motor for next summer
I decided to do some experiment with one of these
Kawasaki John Deere ignition modules to see of what
value they might be to me. The magneto I’m using is from
Pal, Scout, Ranger 1 hp. motor that is also found on other
motors including some small Sea King’s and Johnson’s.
Although small, with the spark plug out, these magneto’s
will produce a spark with a quick twist by hand. Using
the module I was able to produce a spark but am unsure
if it will start and run this motor. The magneto must spin
much faster to produce the same spark as with the points
and condenser.

Wasn’t impressed with the spark when replacing the points
and condenser with just this electronic ignition module.
Occurred to me I may have better luck if I also use a coil
from an electronic ignition as electronic ignition coils don’t
work with Points. Finding something that could be put
on the lams, would be small enough to fit under the
flywheel, and all the wires are located where the don’t
interfere with anything that’s moving is a challenge
with so many to choose from and just pictures to look at.
The first few coils I ordered were of no value size wise
but this one has potential. I chose this magneto because
I had a bad coil to get laminates from. This original coil
is no longer available and there is no substitute known
to me.

Looks like it throws a nice spark! What kind of “Wizardry” is going on with
that spark tester. Is that a vacuum gauge?

These spark plug testers are suppose to be
able to check the spark under pressure
as was one function of these early cleaner/
testers.
However – tester # 1 spark isn’t being
generated buy a spark plug.
Tester #2 can test a spark plug however
I don’t believe either could generate
enough pressure to be of any real use.
I have a collection of devices to check
spark. Some manufactured, others home
made. I use # 1 a lot as (after some
modification) the clips make it easy to
use, I can adjust the gap by turning the
studs the wires are attached to, and
the spark is relatively visible compared
to other testers I have tried. The pump
and gauge have no value other than
something to hold on to in IMO.

Those testers look like something JC Whitney would have sold back in the 70’s.
They had all kinds of “gadgets”, kind of like the back of a comic book, but
for older kids! I always wanted to order the X-ray glass from the comic books,
but never did……. suppose they still have them?

Tubs, as always, great work and thanks for posting. Please keep us informed of developments on the electronic option.
I see potential for an article in the Outboarder

Testers …. It has always been my opinion that you get the same effect as increased air pressure by just increasing the spark gap on a regular tester

Would the new coil you are trying already have a module built into it? If not, it might require twelve volts.
